IMPROVEMENT IN HOSE-BRIDGES.

Specification forming part of Letters Patent No. 1 66,991, dated August 24, 1875; application filed July 31, 1875.

To all whom it may concern:

Be it known that I, LAURITZ T. KRUSE, of New York city, in the county and State of New York, have invented a new and Improved Hose-Bridge for railroads, of which the following is a specification:

This invention relates to an improved portable hose-bridge; and has for its object to protect hose or similar articles that may be temporarily laid across railroad-tracks against injury from the car or other wheels or horses.

The invention consists in the combination of two arched rails, adapted to be placed on the rails of a railroad-track, with a tubularjointed casing that connects the arched rails, as hereinafter more fully described.

In the accompanying drawing, Figure l is a top View of my improved hose-bridge. Fig. 2 is a longitudinal section on the line 0 c, Fig. 1; Fig. 3, a transverse section on the line It It", Fig. 1; and Fig. 4 is a side view of the hosebri'dge, showing it folded together.

Similar letters of reference indicate corresponding parts in all the figures.

The letter A represents a tube open at the bottom, and as long at least as the distance between the two rails of a track. The ends of this tube are also left open. To each end of the tube A, and preferably at right angles thereto, is rigidly attached an arched rail, B and B, the tube A extending under the lower side of such rails. These rails B B are to be placed parallel to each other, and are made one substantially like the other. The connection between the rails B B and the tube A may be established by small plates a a, which are attached to the lower side of the rails B B, and to which the tube A may be riveted,

or the connection may be established in other suitable ways. The arched rails B and B are supplied with pendant prongs b b, 850.,-

which can be driven into the ground to straddle the rails G of the track, and serve to hold the arched rails in place. The plates (1 cl, which connect the pron gs may be hollowed on their lower edges to fit on the rail 0.

The casing A I prefer to make of two pieces of equal length, connected at the center by pivots e, which allows the entire bridge to be folded together, as in Fig. 4, if not used. A hook, f, pivoted to the tube A at one side of the pivots 6 serves to lock the jointed tube in line, as in Fig. 1.

In practice, my improved hose-bridge is placed on a track in such a manner that the tube A covers the part of the hose D that lies between the track, and that is to be protected. The arched rails B B are placed over the rails and securely fastened by driving the prongs into the ground. The arched rails protect the hose against injury by the carwheels, while that part of the hose that lies between the rails will be protected by the casing A from the hoofs of the horses and passing vehicles.

I claim as my invention- In a hose-bridge, the combination of the jointed casing A with the arched rails B B, which have the prongs b b, all substantially as herein shown and described.

The above description of my invention signed by me this 28th day of July, 187 5.
